Tango is a new application for Teams iOS and Android devices which allows free video calling in a way very similar to FaceTime only present among Apple. The Tango Video Calls are free and you can use any Internet connection, either through W-iFi or 3G cellular connectivity for data transmission. The video quality is not the best in the world, but more than decent, and can make free video calls (rather paid by flat rate data we have hired) from anywhere, which is a huge advantage over similar services. Users must create a profile of Tango to interact with the application. once you have created the profile, make calls through the app will be easier. Now what, iPhone users are able to calls smartphone user with Tango, this makes the application feature nice. It is possible turn off the video during a call and continue to transmit audio via VoIP, which is very comfortable. The application will work even on mobile phones that do not have a front camera (for example, the iPhone 3G, a Magic HTC, Motorola Milestone etc), allowing users to share only what they see. The only solution to this problem is to begin to talk in front of a mirror ... the old trick of mobile video calls with no front camera. And in terms of a contact list, the application populates your existing address book. Another strengths of this service is that it is possible to make these calls between terminals of different brands, manufacturers and most importantly, different operating systems. It is possible, for example, a call to iPhone and Android being able to see their faces when speaking, even though both speakers are not using the same operating system on their mobile. Quality of video calls made using Tango is really impressive.The application is free and you can download it from the App Store or the Android Market on your Smartphone. You can download the application by simply clicking here tango.me . If you're an iPhone 4 user does not miss the opportunity to use this application if it is, let us know in the comments. So from now onward start using Tango Video Calls to communicate with your friends.
